CMMVC8715E The command failed because the storage pools for the volume are not in two independent sites. Volumes can only be created using storage in site 1 and site 2.
Explanation
When you create stretched or HyperSwap® volumes with two storage pools, the pools must be located in independent sites, that is, in both site 1 and site 2.
User response
Ensure that you have storage pools in both site 1 and site 2, then retry the command.
